Said PSUs are VERY loud.

probably possible to mitigate both mentioned problems by installing 2xPWS-1K28P-SQ (verification in progress, will update page)

I (Ullbeking) am currently experiment with 2x PWS-1K28P-SQ in my SC747 chassis, as replacements for the 2x PSW-1K41P-SQ that the system came with.

Athena Power RM-3U8G1043

Some motherboard standoffs needed to be removed, and others needed additional hight.

There was no standoff hole for the top right.

The support beam across the top of the case interferes with CPU2 heatsink, but can be easily removed.

Standoff Issues

Stand off issues appear to be a very common problem. In many cases mitigation may be possible.

Fractal Design Define XL R2

Missing standoff holes for the top-left and top-middle positions.

Some alternative standoff in at least the top-middle position may be required to prevent too much bending of the motherboard while inserting RAM.

The positions of some standoffs are under components mounted on the back of the board. Careful measurement and attachment of only the standoffs that fit prior to installation of the motherboard is a necessity to avoid damaging the motherboard upon installation.

An add-on internal USB header is necessary to activate the extra 2 USB3 ports on the front panel.

The case is very spacious, with plenty of room and lots of space for many fans. Works well to provide necessary airflow and pressure within the case.

It is extremely important to have a good quality, powerful fan capable of withstanding high temperatures is required for the rear exhaust fan, which is very close to the rear CPU exhaust. A low quality fan in the rear exhaust port may hinder cooling.

Thermaltake Core W200

Heavy, expensive, massive.

Compatible with caveats

Talos™ II mainboard will fit in E-ATX compatible side only (when viewed from rear of case, the right side) if the dual system case.

Missing standoff holes for the top-left and top-middle positions. (non-essential but ensure proper support when inserting and removing RAM to avoid bending mainboard)

Must remove wire-hole rubber grommets present under Talos™ II mainboard on right lower side for proper fit

also missing top-left standoff hole at least on earlier DS2 revisions (q66, solved by drilling holes for both top-left and top-middle without using plastic standoffs, I sent feedback to Nanoxia in late December 2016 so perhaps the top-left hole was introduced silently)

As a workaround the standoffs can be unscrewed and placed upside-down (screw threads facing up) under the motherboard holes.

This actually works surprisingly well, and thanks to the other screw points the motherboard is rigid enough that I don't worry too much about the weight of the HSFs flexing it.

That said, it's probably a good idea to always transport the system on its side and avoid bumping it if possible.

The hinged panels that open with handles are much nicer than fiddling with thumb screws, but annoying since it makes it slightly trickier to do things that involve both the inside and back panel of the case (e.g., inserting PCI-e cards).

The PSU is at the very bottom of the case, while all the motherboard power connectors are at the very top of the case, so this can cause some issues if your PSU's cables aren't long enough.

The EPS12V cables on my power supply had a few inches left over, but the main motherboard power cable was just barely able to reach from the other side of the case to the power connector.

The front of the case is sheet metal stuck to plastic using some double-sided adhesive tape, which doesn't seem to work very well.

When I received the case the front metal was starting to peel off a few inches (several cm) at the top and bottom.

It sticks back in place when I press on it, but I may need to get some better adhesive and re-apply it later.

For $170, I was hoping for something a little more robust, but at least it's pretty.

E-ATX boards fit, but standoff holes for the top-left and top-middle positions are missing. There's a hole where the top-right standoff is supposed to be, but it's too big to screw in an ordinary standoff.

Ceptagon CP-M1 (Vertical Case)

form factor is weird

It's a really tight fit for e-atx, but it works.

You can fit in a talos 2 lite

a talos 2 probably won't be able to fit without taking off one of the coolers to get the motherboard in, and then putting the cooler back on
